application `nea .ran-nary ia wat. "serial na aora rlFhis inventionrelates to refrigerating apparatus andrefers more particularly vto thebrine tanks thereof.

@ne of the essential objects of the invena tion is to providea tank ofthis type in which the refrigerating medium is adapted to circulatefreely in an intermediate chamber that is preferably disposed between anouter chamber containing the brine or other liquid hav' l@ ing a lowfreezing point, andan inner chamber containing the molds or trays inwhich ice may be formed for table or other use.

Another object is to provide simple and effective doat .operated meansat the top of la the tank for automatically maintaining therefrigerat-ing medium at a relatively high level in the entire chamber.

A further object is to provide a brine tank ,in which the chambercontaining the fluid 20 having a low freezing point is adapted toreceive a container for ice cream ingredients.

Still another object is to provide simple and effective means foragitating the ice cream ingredients while the container therefor is 25vWithin the brine tank chamber containing the fluid having a lowfreezing point.

A further object is to provide a strong and durable tank that is simpleand compact in construction and may be manufactured at a 3Ucomparatively low cost. l

With the above and other objectsin view the invention consists incertain novel features of construction, combinations and arrangements ofparts as will be more fully` 155 described and particularly pointed outin the appended claims.

Referring now to the drawings in which FW like characters of referencedesignate correspending parts throughout the several views, the numeral1 designates a brine tank that is preferably castiron and is providedwith the spaced partit-ions 2 and 3 respectively that lll extendupwardly from the bottomA A of the .'tank'and divide the latter into acentral chamber 5, an intermediate chamber 6, and an outer lchamber.' 7respectively. As shown in Figure 2, ythe partition 3 is preferablylll-shape in 'lll cross section and preferably extends rearwardly fromthe opposite side edges of the vertical opening 8 in `the front wall 9of the tank.v As shown in Figure 3, the partition l -3 terminates shortof the top walllO of the 3U tankv and connects into a horizontal parti-4 tion 11 which connects into the frontwall A 9 of the tank. Located inthe chamber' 5 are spaced horizontal ribs orl shelves 13 which vpreferably extend longitudinally of the partlf allel portions 14 of thepartition 3 and are adapted to support suitable molds or trays\ (notshown) in which ice may be formed for table or other use. lln order thatthis chamber 5 may be normally closed, l preferno ably provide asuitable door 15 that is hinged upon suitable lugs 16 projectingoutwardly from the front wall 9 of the tank at one edge of the opening8. Any suitable means (not shown) position. As shown in Figures 2 and 3,the partit-ion 2 is also preferably lll-shape in cross section andprojects rearwardly from the front wall 9 of the tank. 'llhis partition2 preferably lon extends to the top wall l0 of thetank and is connectedto the side walls 16 by means of spaced vertical transversely extending,webs or partitions 17- which have suitable openings 18 therein throughwhich the brine WF f or other liquid having a relatively low freezingpoint may flow freely. rllhe brine may be supplied to and dischargedfrom the chamber I as desired through suitable conduits (not shown)which are preferably connected lll@v maybe `used to hold the doorinclosedv FF I to suitable inlet and outlet openings 20 and -21respectively in the top wall 10 of the A medium may fiow freely.

tank. Asshown in Figures 1 and 2 the partition 2 is also connected tothe inner partition 3 at spaced points therein by means of the verticaltransversely extendin webs or partitions 22 which have suitable openings23 therein through which the refrigerating moved from the chamber when,the cap is attached thereto. The inlet passage 27 is preferably formedin an inwardlyprojecting enlargement 28 of the cap and is provided Iwiththe spaced longitudinally extending passages 29 and 30 respectively anda vertical passage 31 connecting the adjacent ends of the passages 29and 30. The passage 29 is preferably larger in diameter than the por.`tion 30 and is adapted to Ialoe connected to a suitable dischargeconduit (not shown) while the portion-31 is-relatively small in diameterand is adapted to receive the lower end of a suitable valve 32l Thisvalve has an enlarged stem portion 33 thatis slidably mounted in alignedvertical openings 34 and 35l respectively formed in the enlargement 28and in a horizontal projection 36 extending in wardly from the cap 24immediately below the outlet opening 26; For operating thevalve 32, Ipreferably provide a float 37 having a relatively long arm 38 that ispreferably pivoted on a lug 39 projecting inwardly from the cap 24intermediate the projection 36 and the enlargement28 and that isconnected to the stem 33 of the valve bya pin 40. This pin preferablyextends through the stem and loosely engages aligned elongated openings41 in a bifurcated end portion of the arm 38. Thus the valve 32 will b eoperated by the arm 38 of the float and the movement of the latter willbe controlled by the level of the refrigerating medium inthe chamber 6.

' From the-foregoing descriptionv it will be readily' apparent that theentire chamber 6 is capable of holding a large volume of liquid and itslocation between the outer chamber 7 containing the brine and the innerchanber containing the molds is a. decided advantage over constructionsnow in use, 'for `the reason that the refrigerat-in medium is next toand surrounds the cham r.l containing the ice molds so that the cubesmthe molds will be, frozen quicker and a more vuniformly low temperaturemayl be maintained in the entire body of brine t an is otherwiseobtainable. Moreover the float operated mechanism located vat the top ofthe tank serves to maintain the refrigerating medium at a relativelyhigh level and thus provides a relatively deep coolinfr` surface for thebrine and assists materia ly in maintaining the low temperature desired.Furthermore, it is apparent that the copper coils commonly used forconveying the refrigerating medium through brine tanks of refrigeratingapparatus have been eliminated entirely in my apparatus. It will befurther apparent that all the desired results are obtained by the use4of relatively few parts and that in view of this simplicityofconstruction, the cost of manufacturing such tanks has been reducedtoA a minimum.

In Figures 10 and 11 respectively I have shown av slight modification inwhich the brinetank is preferably formed of sheet metal and is providedat the top thereof with a tubular float chamber 51 containing thtfluidhaving a low -freezing point. In order that the ice creamingredients may be frozen within this chamber I preferably provide atubular casing 52 for receiving a suitable jar or cylinder l53 in whichthe proper ingredients for ice cream may be agitated by a suitabledasher 54. As shown, the tubular casing 52 preferably projects throughthe closed front end of ,the chamber 56 and the front wall 455 of thebrine tank. To provide a strong and durable construction, the casing 52is preferably welded to the closed end 56 of the 'chamber 51 and issecured to an annular flange 57 projecting outwardly from the front wallof the brine tank. The inner end of the casing 52 is permanently closedby a cup-shaped cap 58 while the outer mid thereof is preferably open topermit the jar I or cylinder 53 to be readilyinserted or removed. Aremovable flanged cup-shaped cap 59 is preferably provided for the openend ofthe casing 52 and is preferably provided at the centre' thereofwith a suitable bearing opening 60 for the shaft 61 of the dashcr 54.This shaft 61 also extends through a suitable cup-shaped cap 62 thatthreadedly engages the outer open end of the jar or cylinder 53. Thisshaft is adapted to be rotated by a suit'- able. crank 63. When thiscrank 63 is used, the usual door 64 of the refrigerator is open.However, when it is desired to rotate the. dasher 54iwhen therefrigerator door is closed. the crank 63 is removed from the shaft 61and I referably use an extension 65 that is apphed to the free endof theshaft 61 and-cxtends through the door 64. Any suitable means such as thecrank 66 may then be applied to the extension 65 torotate the dasher.

With thisconstruction, two chambers 67 ,for

innata the bottom of the brine tank while a suitable N idoat 68 ispreferably located atthe bottom f of the chamber 51. y

lln llfigures l2 and 13 ll have shown another modification wherein theHeat chamber 70 is. located atl the toppof the brine tank similar to thechamber 5l but is preferably welded yto the front and rearwalls 7l. .and'l2 respectively of the brine tank. With this construction, the doatchamber 73 is preferably located within the chamber 70 but is positionedabove the tubular ice cream casing (not shown) hile it is believed thatfrom the foregoing description the nature and advantages of theinvention will be readily apparent, ll desire to have it understoodvthat ll do not ,L limit myselfto what is herein shown and described, andthat' such changes may be resorted to when desired as fall within thescope of what is claimed.
